Key Industry Challenges
“Electricity cost, not electrolyser efficiency, is the biggest factor in hydrogen economics.”
Energy&Fuels, 2025
Despite falling renewable costs,
green hydrogen projects are still stalling or getting shelved in Australia and beyond. Lets explore why.
The Hidden Cost of Conventional Electrolysers
Most electrolysers today remain grid-tied, battery-reliant, and expensive to operate — unable to ramp fast enough to match sudden surges in wind or solar. This mismatch leads to wasted energy and higher costs for plant operators.
When Current Electrolysers Can’t Keep Up
Hydrogen plant operators still bulk pay for every kilowatt generated, whether used or not. This lag brings down efficiency, drives up production costs, and lowers energy utilisation — slowing commercial deployment.
Conventional Electrolyser Technologies Include:
Alkaline Systems (ALK)
• Grid-dependent
• Struggles with renewable intermittency
Anion Exchange Membrane (AEM)
• Short lifespan
• High Operations & Maintenance costs
Proton Exchange Membrane (PEM)
• Relies on expensive noble metals
• Requires high-CAPEX infrastructure
Our Approach
“The most affordable hydrogen doesn’t come from the grid—or from battery-backed systems. It comes from off-grid, battery-free configurations with low-CAPEX electrolysers.” Energy&Fuels, 2025
At AquaLux, we’re changing the economics of green hydrogen by removing costly infrastructure burdens and inventing the system from first principles.
Our modular microfluidic electrolyser is:
• Off-grid
• Battery-free
• Low-CAPEX and noble-metal-free
• Built for volatile, real-world conditions
It ramps to full load in seconds – not minutes – syncing with the natural variability of solar and wind to eliminate energy waste, boost utilisation, and reduce costs.
Our Technology
At the core of AquaLux’s breakthrough is a patented, first-of-its-kind microfluidic electrolyser — purposefully designed for real-world, scalable deployment.
By holistically modelling over 6,500 configurations, we’ve identified the optimal scenario for the lowest Levelised Cost of Hydrogen (LCOH) — achieving what the industry long deemed impossible: affordable, off-grid green hydrogen.
Protected by patents across our proprietary microfluidic architecture, system integration, noble-metal-free electrodes, and control logic, AquaLux is designed for safe, reliable performance — without the fragility or infrastructure burden of conventional technologies.
Affordability in OPEX & CAPEX
• Off-grid, battery-free, and low-CAPEX
• Eliminates gas purification and separation systems
• Hydrogen crossover-free → higher efficiency, lower OPEX
• 70%+ efficiency; cold-start to full load in seconds
• Low-cost intermittent renewables → fast ramp-up, prevents energy loss, and lowers OPEX
Intrinsic Safety
• 99.99% hydrogen purity
• Hydrogen crossover-free → no gas mixing or explosion risk
• No gas purification required
• Lower system complexity
• Intrinsically safe for remote or off-grid environments.
Durable and Low Maintenance
• Catalyst-free → no bubble-induced delamination
• Electrodes last up to 10 years → longer life, fewer replacements
• Smart design bypasses faulty components
• Maintains 80%+ capacity even when at fault
• Minimal maintenance — no on-site labour required
Scalable & Flexible Deployment
• Modular design for scalable growth
• Rapid deployment → faster delivery at any scale
• Mass-manufacturable and easily reconfigurable
• Simplifies setup, scaling, and ongoing maintenance
• Automated digital maintenance offsite
Sectors We Power
Our Vision
At AquaLux, we’re not just delivering on the “green” promise — we’re making green hydrogen truly cost-competitive for the first time.
We’re building a cleaner, more resilient industrial future — powered by innovation, not compromise.
